Definitions

  • This invention relates to devices for the purification and reclamation of lubricating mineral oils.
  • a large part of contaminants found in used lubricating oil is constituted by foreign materials such as water condensed from air moisture, products of fuel combustion, fuel dilution, and products resulting from chemical action within the system such as products of partial decomposition of oil and incomplete combustion of fuel which have a lower boiling point than the mineral lubricating oil.
  • these products are boiled off under suitable temperature conditions. Normally, a certain amount of purification is achieved in an internal combustion engine which is allowed to run at a relatively high temperature.
  • the principal object of this invention is to provide a device for the treatment of heat process of used lubricating oils.
  • Another object of this invention is to provide such a device that can be operated on-line in conjunction with an internal combustion engine.
  • a further object of this invention is to provide a device for a continuous on-line refining of the lubricating oil of an automotive engine.
  • An additional object of this invention is to provide such a device installed as a bypass between the pressurized oil circuit and the crankcase of the engine.
  • Figure 1 is a perspective view of the refining apparatus
  • Figure 2 is a cross sectional view of the interior structure of the apparatus
  • Figure 3 is a diagram showing the oil flow between the heating vanes inside the apparatus
  • Figure 4 is a top view of a horizontal cross section of the lower half of the vapor outlet
  • Figure 5 is a cross sectional view of the vapor outlet taken along a vertical diametrical plane
  • Figure 6 is a partial cross sectional view similar to Figure 5 showing the vapor cutlet in the tilted, closed position. Description of the Preferred Embodiment of the Invention
  • an oil refining apparatus 1 designed to operate in combination with an internal combustion engine.
  • the refining apparatus 1 comprises a canister 2 which is preferably mounted alongside the engine.
  • an inlet 6 normally connected by conducts to a section of the engine containing pressurized oil, preferably near the outlet side of the oil pump. This is most effectively done by tapping by means of a T-connector between the engine block and the oil pressure sensor.
  • an outlet 7 designed to be connected to the engine crankcase.
  • the inlet conduit and orifice 6 should preferably have a quarter inch (6.25 millimeters) diameter.
  • the outlet conduit and orifice 7 should preferably have a one-half inch (12.5 millimeters) diameter.
  • a sealed housing 10 in the shape of a cylindrical column.
  • a vapor outlet 24 capped by a safety tilt valve 8.
  • Inside the cylindrical housing 10 is a heating element 9 comprising a resistance 11 immersed into a heat conductive fluid 12 not unlike the so-called transformer oil.
  • the chamber inside the canister 2 is divided by a series of horizontal, disc-shaped vanes 17 extending radially from the cylindrical housing 10.
  • the cylindrical housing 10 and the vanes 17 are made of a highly heat-conductive material such as copper, and each vane 17 is intimately bonded to the cylindrical housing 18.
  • This bonding may be achieved by brazing each metal vane 17 to the cylindrical housing 10 or by threading the cylindrical housing 10 on its entire length as well as the hub of each vane 17, and then bolting the vanes 17 on the column at regular intervals.
  • Each vane 17 has two orifices 18 pierced through it at diametrically opposed locations on each side of the cylindrical housing 10. The orifices are oriented such that they are located 90° apart from the orifices of the adjacent vanes.
  • the thickness of the vanes 17 and the spacing between them is preferably one-eighth of an inch (3.127 millimeters).
  • the diameter of each orifice is preferably one-quarter inch (6.25 millimeters).
  • the heating element 11 is connected to a source of electrical power such as the battery of an automotive vehicle by means of electrical conductors 14, 15 and 16.
  • One conductor 15 is run through a thermostat 13 which senses the temperature at the outlet 7 of the canister 2. When that temperature reaches a certain predetermined level, the electrical path between conductors 15 and 16 is interrupted.
  • the pressurized oil coming from the engine will enter the canister through inlet 6 and flow through the inside chamber following a circuitous path from one vane to another as better illustrated in Figure 3. Heat from the heating element 11 transmitted through the vanes 17 increases the temperature of the oil causing the evaporation of the volatile contaminants contained in the oil.
  • the oil flows out of the canister 2 through outlet 7 and is returned to the engine crankcase.
  • the difference in diameter between the inlet 6 and the outlet 7 guarantees that the oil level inside the canister will never exceed the level of the outlet 7. Vapors from contaminants escape through the outlet 24.
  • the thermostat 13 is preferably selected to permit the oil to reach a temperature of approximately 750o Fahrenheit (400° Celsius).
  • the arrangement of the vanes 17 and the size of the orifices 18 assures that the oil pressure is progressively decreased as the oil flows upward through the chamber inside the canister 2.
  • the safety valve 8 mounted above the vapor outlet 24 is designed to close in case of the accidental upsetting of the canister 2 in order to prevent the oil from spilling out of the canister.
  • the valve comprises a ball 20 normally sitting on top of four support vanes 21.
  • Vapors from the canister can escape from the ball 20 by circulating between the vanes 21. They then proceed through a valve seat 22 into the upper part of the valve 19 and through venting ports 23. If the canister 2 is upset, the ball 20 rolls toward the valve seat 22 completely obstructing the exit path.
  • the dimensional considerations given herein are generally applicable to refining apparatus designed to operate in combination with an automobile engine. Their absolute value and respective ratios may have to be adjusted in other applications as a function of engine size and the degree of oil reclamation desired. An excessive flow of oil through the refining apparatus may cause intolerable loss of oil pressure in the engine. On the other hand, a very limited bypass diversion of the oil toward the refining system will not provide a sufficient degree of refining and will not avoid accumulation of volatile contaminants in the oil if the engine is used during only very short periods.

Abstract

Un dispositif de purification d'huile de lubrification est combine a un moteur a combustion interne. Monte sous forme de bipasse entre la sortie de la pompe d'huile et le carter, le dispositif raffine l'huile contaminee en eliminant par ebullition dans une plage de temperature appropriee les substances contaminantes telles que l'eau condensee, les combustibles dilues, et les produits resultant de la decomposition partielle de l'huile. Le dispositif comprend une chambre fermee (2) recevant de l'huile sous pression au fond de la chambre (2). L'huile est forcee de passer dans un labyrinthe forme par une pile d'aubes circulaires (17) avant de sortir a proximite du sommet de la chambre (2) et de revenir au carter. Un element de chauffage electrique (11) commande par un thermostat (13) chauffe les aubes (17) a une temperature requise pour extraire par ebullition les substances contaminantes. Les substances contaminantes vaporisees peuvent s'echapper par un event (23) dans la partie superieure de la chambre (2).
